Abstract
The utility model discloses a coaxial cable connector used in microwave communication. The coaxial cable connector comprises an outer conductor, an insulator and an inner conductor. The outer conductor comprises a shell and a connecting nut which is connected to the shell. An inner diameter of the shell is a three-stage stepped hole whose front end aperture is larger than a back end aperture. A shell front section is directly used as a connection section which is connected with an external coaxial device outer conductor. An inner wall of a connecting section of a shell back section is provided with a spiral groove, and an outer wall of the shell is provided with a small hole which is communicated with the spiral groove. Compared with a traditional structure, the coaxial cable connector has the advantages of small size, light weight, simple connection structure and connection process, convenient processing, and low manufacturing cost, installation is simplified, a matching link which influences a performance parameter is reduced, the stability of the performance parameter is raised, through actual detection, a standing wave ratio of the coaxial cable connector is superior to that of a traditional structure product, an index third-order intermodulation is controlled well, and consistency is significantly improved.
Description
Technical field
The utility model relates to a kind of coaxial cable connector that uses in microwave communication.
Background technology
Coaxial cable connector is usually by by with the inner wire 02 of contact pin or jack, partly form at outer conductor 01 and interval insulator 03 between inner wire and outer conductor of periphery etc.In the existing structure as shown in Figure 1, outer conductor 01 is comprised of housing 011, the attaching nut 012 that is connected to the housing leading portion usually.Its insulator is usually jointly spacing by the step on the inner and outer conductor, simultaneously usually is provided with insulation spacer 04 at the housing back segment with the part that is connected of coaxial cable, and scolder inflow housing leading portion causes short circuit when preventing that coaxial cable and housing are welded to connect.The defective of this structure is: 1, product parts is more, and volume is large, assembling inconvenience, and the set-up time is long, has increased cost; 2, owing to cooperate link many, complicated to the influencing factor of performance parameter, performance parameter is stable not, and consistency is poor, and especially three these indexs of Jie's intermodulation often are difficult to reach instructions for use.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, easy for installation, coaxial cable connector that performance parameter is stable.
In order to solve the problems of the technologies described above, coaxial cable connector of the present utility model, comprise and be coaxially arranged with outer conductor, insulator and inner wire, outer conductor comprises housing and the attaching nut who is connected on the housing, the internal diameter of housing be the front end aperture greater than three grades of shoulder holes in aperture, rear end, described housing leading portion is directly as the linkage section that is connected with outer, coaxial device outer conductor; Have one section helicla flute on the inwall of the linkage section of described shell back segment, have an aperture that communicates with helicla flute at the outer wall of housing.
Described insulator is arranged between housing and the inner wire, described insulator rear end is by the middle one-level ladder step location on the inner walls, be provided with simultaneously the hangnail at the bossed tip of tool on scala media halfpace rank, the tip of hangnail penetrates in the matrix of insulator.
After adopting above-mentioned structure, because afterbody adopts helical structure, need not to use insulation spacer, cable welds after directly screwing in shell, scolder can be deposited in the helicla flute and can not flow to the housing leading portion, thereby the phenomenon of short circuit can not appear causing owing to soldering tin amount is excessive, greatly improved the intensity and the electrical contact performance that connect; Simultaneously, insulator positions by ladder step and hangnail, also can satisfy positioning requirements.
The utility model is compared with traditional structure, not only volume is little lightweight, syndeton is with to be connected technique simple, easy to process, low cost of manufacture, and simplified installation, and having reduced affects the cooperation of performance parameter link, improved the stability of performance parameter, detected through reality, standing-wave ratio is better than the traditional structure product, this index of third order intermodulation has obtained good control, and consistency significantly improves.
